Hi

iam doing my M.Phil and my research area is Image Processing and
specifically "TEXT EXTRACTION FROM IMAGES"..


Can u give me some ideas based on this..

from the papers already i gone through i can able to understand only
the THEROTICAL Concepts..


I dont know to apply PRACTICALLY


eg.. After detecting text in an image put bounding boxes but my big
doubt is how to put bounding boxes around the text?
how to write MATLAB code for it.. i dont have any idea sir...


Wat i have done through is
1.If it is color image convert to grayscale image
2.By thresholding i convert to binary image..
3.Then applying edge eg..sobel,roberts etc i can highlight the text
area..


tats it..


but how to extract only the text pixels in an image..


kindly help me

Thanx in advance

You are delving into optical character recognition -- OCR. Although good
results have been achieved, the problem is not completely solved despite
decades of work. You have a lot of reading to do. I wish you luck.

You might find software at http://www.simpleocr.com/ interesting.

I doubt that this is a task for Matlab.
